endfaesmandbula in' curled under and around the end portions of theframe ID as at I9. To maintain these end plates in an upstandingposition relative to the frame, the curled portion I9 is spot welded ata number of accessible points to the frame ID.

The ends I5 of the pan are extended upwardly beyond the frame and alongthe inner surfaces of plates I 8 in a smooth unbroken fashion and arecarried over and around the upper edges Aof the plates. To strengthenthe upper edges 20,

said edges are folded over as shown at 2|, and

in so folding, the edges 22 of the extended end walls I5 are pinchedsecurely in place. Side edges 23 are similarly folded and are preferablyso folded before top edges 20 are'folded. This construction of plates I8and end walls I5 results in a rigid support for a superposed pan with nointerruptions in the surface of the receptacle. A

The ends of the curled base I9 of each plate I8 are split and the lowerportion thereof is then bent downward to form a lug 21|.` These lugsfunction to prevent sidewise movement of one pan relative to the other.The upstanding plates I8, of course, serve to preventA relativeiendwisemovement between the pans. .y

Referring more particularly to'` Figs. l0 and 11, it will beobservedthat the, lug 24 is formed by flattening the bottom Iportion of'the curled edge I9. This portion is then stiffened by forming a bead 25therein which extends for some distance parallel with the frameand ,thendownward along the center of the lug. It is readily apparent thus thata' considerable number of pans made in accordance with this inventioncan be readily stacked one upon the other into a pile which does notshift as pans are added.

The pile thus remains stable and balanced andl the inner face of one panis held out of Contact with the next higher pan,

A modified form of construction is shown in Figs. 5 to 9, inclusive. Inthis modified form two or more pans of the type described are unitedside by side so as to be handled as a single unit. i This isaccomplished by the provision of a pair of straps 26 which are rigidlyconnectedwith ,the plates 21 of the individual pans, such' plates 2lcorresponding withthe plates I8 ofthe pans shown in Figs.Y l'to 4. jAsis shown in Fig. 8, the top and bottom edge portions of the plate 26 arefolded to provide flanges 28 and 29 for reinforcing thestructuratheflanges 28 and 29 in the arrangementshown being flush with the face ofthe intermediate portion of the plate.

As shown in Fig. 7, the upper edge portions of the plates 2'Iv areinterlocked with the upper edge portions of theend wall portions I5, thestrap 26 being preferably securedto plates 21..by rivets 3|. As isbestshown in Fig. 7, the inner heads of the rivets 3| are iiushwith theinner surface of the plates 21, so that-such rivets do not extendthroughthe 'end walls I5 of the pans. The plates 21 are welded to theframes I I) to prevent turning movement `of` the plates. As is clearlyshown in Figf'G, the outer ends of. the plates 21 are provided with lugs24for preventing sidewise movement ofthe pans relative to one another.In the arrangement shown, the inner ends of the plates 2l are notprovided with lugs24. w

`It is apparent that the pans shown are rugged but inexpensiveto make.vSince the lugs-areV integral with the supporting platesthey donot comeloose or get out of adjustment; ,The method of attachment of the platesto the frame makes possible a smooth inner surface for the pan which ishighly desirable.

It is understood that the foregoing description is merely illustrativeof a preferred embodiment of the invention and that the scope of theinvention therefore is not to be limited thereto but is to be determinedby the appended claims.

I claim:

1. yA baking pan comprising a reinforcing member having oppositelydisposed portions rigidly connected together, a sheet of metal folded toform the Walls and bottom of the pan, and upstanding plates rigidlysecured in position with theirglower edges curled around opposedportions of said reinforcing member, said sheet having 'extensionspassing upwardly along the inner faces of said plates` with their upperedge portions curled about the upper edge of said plates. 2. A bakingpan comprising a reinforcing rod bent into form to provide oppositelydisposed portionsrigidly connected together, a sheet of metal folded `toform thewalls and 4bottom of the pan, ups'tandingj plates rigidlysecured in position with their loweredges'curledaround opposed portionsof the rod, and extensions on said sheet passing upwardly along theinner faces of said platesfwith the upper edge portions of the platesand ,extensions curled together in interlocking engagement with eachother. i V l 3. A baking pan comprising'fa reinforcing rod bent into theform of a closed figure, a sheet of metal folded to form the walls andbottom of the pan, said sheet being curled outwardly over opposedportions of the rod,- opstanding plates curled aroundother opposedportions of the rod, and extensions on said sheet passing upwardlyadjacent said plates andaround the upper edges thereof, saidV upperedges of the plates being folded so as to pinch the edges of theextensions between theirfold's; u

4. A baking pancomprising arectangular reinforcing memberV havingoppositelydisposed portions rigidly connectedltogether, a sheet of metalfolded to form the walls and bottom of the pan,` the side wall portionsof said sheet being curled outwardly over said reinforcing member, andupstanding plates `on the outer faces of the end wall portions ofsaidsheet Ahaving their lower edge, portions curled around opposedportions of said reinforcing member and rigidly connected therewith forpreventingthe plates from moving with respect to said reinforcingmember. 5. A baking lpar; comprising a* reinforcing member havingoppositely disposed portions f rigidly connected together, a sheet ofmetal folded to form the Walls and bottom of the pan,

- saidsheet being curled outwardly over a portion of said reinforcingmember, upstanding plates curled over opposed portions of saidreinforcing member, and depending lugs on said plates formed integrallywith the curled portions of the plates and having stiffening beadstherein.

6. A multiple pan arrangement comprising a plurality of pans each havinga reinforcing member formed with oppositely disposed end and sideportions rigidly connected together,v and each formed from a sheet of'metal folded to form the walls and bottom of eachpan, with the sidewalls curled outwardly over the adjacent parts of the reinforcingmember, upstanding plates curled around the end portions of thereinforcing member ofeach panand stii straps at the ends of the panssecured rigidly to said plates for holding thepansinspaced parallelrelation.

7. A multiple pan arrangement as described in claim 6said plates beingfolded over the upper edge of the strap to reinforce said strap thereat.8. A multiple pan arrangement as described in claim 6, said strap beingfolded at its lower edge to stiffen it thereat.

9. A multiple pan arrangement as described in claim 6, said plates beingfolded over the upper edge of the strap to reinforce said strap thereat.

in claim 6, in which lugs are formed integrally with the curled portionsof saidupstanding plates for holding the multiple pan arrangement inspaced relation to a similar multiple pan arrangement stacked therewith.

13. A multiple panarrangement as described in'claim 6, in which saidupstanding plates are secured rigidly to said reinforcing member forpreventing their movement out of supporting position.

14. A multiple pan arrangement comprising in combination a plurality ofpans arranged side by side in spaced relation to each other, upstandingplates rigidly secured in position to form upward extensions at the endsof the pans with the end walls of the pans also extended upwardly at theinner faces of said upstanding plates in mutually reinforcing relationthereto, and straps extending across the ends of the pans and securedrigidly in position on the pans by securing devices passing throughv thestraps and through the upstanding plates so as to leave the end wallsintact.
